1. February 2007 NASA Dryden Status Aerospace Control & Guidance Sub-committee Boulder, CO February 2007 John Bosworth (661) 276-3792 John.bosworth@nasa.gov

2. February 2007 Autonomous Airborne Refueling Demonstration (AARD) Sierra-Nevada Corp. working more robust algorithms with 2 of 3 successful with 100% miss recognition Took fuel with autonomous disconnect Successfully demonstrated plugging with rendezvous –2 mi dist, 60 deg off centerline Soon will demonstrate refueling in a turn Autonomous probe and drogue airborne refueling F/A-18 configured as autonomous testbed Pallet on tanker, otherwise unmodified Relative GPS/INS navigation Monocular camera tracking system

3. February 2007 Ikhana Project Update Flying 3-4 flights per day for pilot training at Grey Butte Preparing for Western State Fire Mission this summer Ames USFS ARTS III research controller hardware is ready. Software is being developed Combined aircraft and payload commands Sensor fusion (IVHM) Intelligent mission management GA is developing software to accept “ground station” commands from the on- board ARTS III research controller Mission plans Autopilot hold commands Stick, Rudder and throttle commands

4. February 2007 Quiet Spike F-15B with Quiet Spike Extended Flight Test Completed –No SMI extended or retracted (despite ground test predictions) –Envelope cleared to M 1.8  Small effects on stability, CAS on  Damping derivatives reduced significantly - Cmq near zero at M 1.8 - Marginally acceptable CAS Off HQ predicted AIAA 2005-1015 Joint program with NASA & Gulfstream

5. February 2007 F-15 Intelligent Flight Control System Completed space- based range testing Completed Quiet Spike probing flights Returning to IFCS flights in March –Larger canard multipliers –HQ metrics for asymmetries Working improved direct adaptive neural network Sim CAT 42 Sim CAT 43 Sim CAT 47 Sim CAT 51 Sim CAT 53 Sim CAT 50 X X X X X X X X X X X X X Pitch due to Roll Roll due to Pitch Coupling Metric Developed for Rotocraft

6. February 2007 F-15 Intelligent Flight Control System Investigating PIO tendency Driven by roll-to-pitch weight Errors due to PIO not large enough to move roll weights Trade off between dead zone and sensitivity

7. February 2007 C-20A Precision Autopilot Development Goal: Fly for up to 200 km within a 10 meter tube with light turbulence Status –Flight Readiness Review Board briefed December 2006 –Formal Software Qualification completed February 2007 –Precision Autopilot Demonstration flight early 2007 Monte Carlo Simulation Results Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR)

8. February 2007 X-48 Blended Wing Body Low speed taxi tests completed in Dec 2006 Verification and validation of flight software is 75% complete Flight readiness review scheduled for mid Mar 2007 Potential testbed for future ARMD work
